How to judge the quality of silicone rubber heaters

Firstly, we need to know the basic characteristics of better silicone rubber heaters, and summarize them into two aspects:

1. The electrical performance of the silicone rubber heater is normal

After the carbon fiber silicone rubber heater is powered on, the power stabilizes within a certain allowable range during frequent startup, shutdown, and long-term continuous operation, without any instantaneous power impact. Silicon rubber heating plate heating element: Wrap nickel alloy heating wire around glass fiber, heating power can reach 2.1W/c ㎡, heating more evenly. Moisture and chemical resistant silicone rubber material provides a longer heater lifespan. Pressure sensitive adhesive can be used to bond flat and smooth workpieces. New energy vehicle battery heater solves the heating system solution for low-temperature environment charging of power batteries: The silicone heating system is a thin and pure resistive heating element, which is very soft and has a thickness of 1.5mm. Silicone rubber waterproof heating pad is a type of thin sheet that generates heat when energized. The core is made of nickel chromium wire or nickel chromium foil etched into a certain shape, so it has high reliability. It is generally printed on insulation materials with any paste such as graphite paste and resistance paste.

2. High thermal conversion rate is a key factor in the performance of silicone rubber heaters.

High thermal efficiency, more than 30% energy saving compared to ordinary metal heat exchangers, faster heating speed. Carbon fiber heat exchangers are a type of pure blackbody material with characteristics such as fast heating, small thermal hysteresis, uniform heating, long heat radiation transfer distance, and fast heat transfer speed.

How to judge the quality of silicone rubber heaters? In fact, a more intuitive way to verify the quality of silicone rubber heaters is to first wipe the surface of the silicone rubber heater, then turn on the AC 220V power supply, dry and burn in the air, turn off the power after the surface turns red, completely cool the silicone rubber heater, wipe it with napkins, and the white paper should be free of black oxide powder (not reacting with oxygen in the air), marked as a high-quality silicone rubber heater. On the contrary, it is poor quality.
